Depressive disorder, is a mood disorder caused by social and psychological factors, mainly characterized by persistent bad mood and sullenness. According to relevant surveys, if we take a year as a unit, the number of people suffering from depression each year is 10% of the population, and women are twice as many as men. Regardless of ability, age, poverty or wealth, everyone is likely to suffer from depression. In modern social life, depressive mood disorders are as common and common as the flu. For this reason, depressive disorders are called “mind colds”, or “mood colds”. If you have been depressed for the past two weeks, showing sullenness or sadness, with 4-5 of the following descriptions, then you are likely to have depressive mood disorder. ● Diminished interest in daily activities and recreation, not experiencing the original pleasure and enjoyment. ● Significant lack of energy, slowness of movement, and constant fatigue for no apparent reason. ● Decreased self-esteem, often with low self-esteem, self-blame or guilt. ● Difficulty in associating, or a marked decrease in the ability to think for oneself. ● Insomnia, early awakening, or excessive sleep. ● Loss of appetite or significant weight loss. ● Significant loss of sexual desire. A feeling of lack of meaning and value in life, and a sense that life is meaningless. ● Headache, backache, or unexplained physical discomfort and pain. ● Prolonged feelings of helplessness. Depressive mood disorder is not the same as mental illness, and it will not develop into mental illness, so there is no need to panic if you are depressed, but it is important to detect and seek treatment early. The key to dealing with depression is psychological adjustment, and it is best to seek help from a psychiatrist in a timely manner. For some patients with severe depression, medication, combined with psychotherapy, can achieve the best therapeutic effect.
